"For an ideal chainline on a regular 9-/10-speed freehub body in connection with the Pinion rear cog we have 23mm between hub body and the cog and 4,5mm between the cog and the lock ring for the freewheel body. "

Thanks for that. I've got a 26mm spacer fitted and thought it was almost spot on but obviously not. Oh well better go and order some more spacers.

I´ve been asking durus (owner of the white Ion 18) to give some feedback to the PINION P1.18 gearbox in detail, and he made a sophisticated write-up at MtB-News.de, in German. So feel free to translate it online.

In addition, the PINION peeps provided an interesting explanation of some peculiarities while changing gears 6-7 and 12-13, resp. noises.

Wowbagger (owner of the green ano Helius AM) was so kind to give another sophisticated PINION P1.18 feedback, according to durus´ outline at MtB-News.de. Again, feel free to translate it online.

This gearbox Pinion is great and my bike is just whaooo! Great i love it! I ride 650b for the first time and it's my favorit wheel size, very good rolling skill close to à 29er and more reactive and agyle i think that 650b take a real place in enduro bike .

After some more tripps and a good setup the suspencion i can say that the pinion is working fine.
Upshifting under load is possible exept shifting from 6 to 7 and from 12 to 13 gear must the load hold on for a mili second. Downshifting under load is possible to a limited load but you can feel it by the force to twist the shifter is getting to high. The ratio between the gears is liniar with (so the manual) 11,5% and i find it so positiv to bike uphill.More coming soon

I got my FR off Neil a while ago.... And maybe off to see about a new purchase soon too haha... Although still gutted the wine shop across the road closed.. A bottle of red and a perv at posh bikes always made a trip to ripon a success haha

What size sprockets(how many teeth) are people running on their Helius Pinions? Is there a minimum size you need to run?
I have 30 or 24 front and 21 or 26 for rear. What should I use?
These weren't supplied by Nicolai(already had Pinion). But I have Pinion stock from work.
